Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] The present invention is a hydraulically driven modular pump frac skid, such as figure 1 , figure 2 , image 3 As shown, the power skid 1 and the fracturing pump skid 6 are included, and the bases of the power skid 1 and the fracturing pump skid 6 are both provided with V-shaped connecting lugs, which are connected by a pin 25 . The front end of the power skid 1 is provided with a vertical radiator I2, the middle is provided with a main engine 3, and the rear end is provided with an auxiliary engine 4 and a hydraulic system I18. The auxiliary engine 4 is directly connected to the hydraulic pump of the hydraulic system I18 through a shaft coupling and a fixed flange. One way of the hydraulic system I18 drives the radiator I2, and the other way is used for starting the main engine 3 . The main engine 3 is connected to the gearbox 5 o...

Abstract

The invention discloses a hydraulic driving modular pump fracturing sled. The hydraulic driving modular pump fracturing sled comprises a power sled and a fracturing pump sled, a main engine and an auxiliary engine are arranged on the power sled, the auxiliary engine is connected with the hydraulic pump of a hydraulic system I in a transmission mode, one oil circuit of the hydraulic system I is connected with the driving motor of a heat sink I, and the other oil circuit of the hydraulic system I is connected with the starting motor of the main engine; a gearbox is arranged on the fracturing pump sled, the main engine is connected with the input end of the gearbox in a transmission mode through a transmission shaft, a plurality of corner boxes in series are connected to the output end of thegearbox in a transmission mode through a universal shaft and a clutch in sequence, the corner boxes are connected with a plurality of hydraulic pump sets in series in a transmission mode, the hydraulic pump sets are connected with modular pumps in a transmission mode, the multiple modular pumps are arranged in parallel on the lower middle portion of the fracturing pump sled, the multiple modularpumps are in connection by means of an integral connecting frame, and integral output blocks are connected to the discharge ends of the modular pumps. The problem is solved that in the prior art, themaintenance cost is high.

Description

technical field [0001] The invention belongs to the technical field of petroleum, coal bed gas and shale gas equipment, and relates to a hydraulically driven modular pump fracturing skid. Background technique [0002] As the core equipment on the ground for reservoir fracturing, the fracturing truck’s main function is to inhale fracturing fluid, discharge it after pressurization, and inject it into the bottom of the well to perform fracturing on the reservoir. Large-scale fracturing vehicles usually adopt a self-propelled vehicle-mounted structure, which consists of two parts: a chassis vehicle and an upper-loading equipment. This vehicle-mounted structure mainly has the following characteristics and existing problems: 1) There are many components, large volume, high ground clearance, difficult maintenance, large size and heavy weight, and it is an over-limit vehicle. 2) The power density and reliability requirements of core equipment such as chassis, engine, gearbox, and f...
